cruise when not desired. Keep the
cruise button turned off when cruise
control is not being used.

pedal.
Resuming a Set Speed
If the cruise control is set at a
desired speed and then the brakes
are applied, the cruise control is
disengaged without erasing the set
speed from memory.
Once the vehicle reaches about
40 km/h (25 mph) or more, move the
thumbwheel up toward RES/+
briefly. The vehicle returns to the
previous set speed and stays there.
Increasing Speed While Using
Cruise Control
If the cruise control system is
already activated,
Move the thumbwheel up toward
RES/+ and hold it until the
vehicle accelerates to the
desired speed, and then
release it.
To increase the speed in small
amounts, move the thumbwheel
up toward RES/+ briefly and
then release it. Each time this is
done, the vehicle goes about
1.6 km/h (1 mph) faster.
